Game Jam is a community event hosted by Jagex that showcases potential upcoming content, made by Jagex Moderators in a weekend-long hackathon. Jagex Moderators show early stage development of their ideas for content during livestreams, as well as taking player feedback and suggestions for future updates.
Game Jam 2018 took place on the weekend beginning 14 April, with Jagex Moderators being given time on the Thursday, Friday, Saturday and Sunday to develop their ideas. Livestreams were broadcast on 14 and 15 April. Game Jam project related channels were set up in the official Jagex Discord server.
The 2017 Game Jam coincided with the February 2017 Double XP Weekend. There were two livestreams, at 15:00 UTC on the 18 and 19 February. An official Game Jam Discord server was created for players to discuss content with developers.
